You're responding to arguments I didn't make.
If you think Trump is solely blaming the losses on the pro-life movement, I invite you to visit his Truth Social where he points out claims and evidence that the elections were stolen daily.
That said, there is still room to point out people doing things wrong, like how many pro-lifers took the win and then didn't fight to maintain it, and how many Republican candidates botched the issue by allowing themselves to be painted at extremists without a counter. Which is what he did.
You're right about a lot - but your claim that he blamed the losses on pro-life voters is not correct.
